Heavy duty conceptDesigned for productivity
The Atlas Copco DM30 is a crawler mounted, hydraulic tophead drive, multi passdrilling rig featuring a 30 ft (9.1m) drill pipe change and a 2-rod carousel. With astarter rod under the rotary head and the optional 4-rod carousel, the DM30 hasa total depth capacity of 150 ft (45.7 m).
It is designed to handle a 4" drill pipe and can handle up to a 5" drill pipe. The drill has a weight on bit force of30,OOOlb (13,600kg),
and both a low and a high pressure compressor alternative are available for the DM30 series, making it suitable for rotary or DTHdrilling applications.
Tower and pipe handlingRaising the tower with a full complement ofup to five drill pipes in the tower can be ac-complished in less than one minute (maxi-mum number of pipes is contingent upon pipesize selection). The carousel-type drill pipechanger is part of the tower assembly and islocated on the outside of the tower frame.Tower pinning and pipe changing is per-formed remotely from the operator's cab.Breaking pipe joint is done by a hydraulic po-sitioned sliding fork wrench with limited im-pact that minimizes shock loads on the tower,carousel. rotary head and feed components. Ahydraulic motor and ratchet rotates the carou-sel to index the drill pipe under the rotaryhead for changing. An exclusive "keylock" ca-rousel design securely locks in the drill pipe atboth the bottom and the top of the carousel toensure maximum safety for drill pipe storageand changing. An auxiliary hoist is providedas standard for the drill pipe and accessory.handling. A safety rod catcher also comesstandard. The DM30 utilizes a hydraulic feedcylinder that raises and lowers the rotary headby way of cables for both pulldown and pull-back. The two work together to raise and low-er the rotary head smoothly and positively.
Rotary or DTH drilling
The DM30is designed to handle a 4" (102 mm) drill I
pipe, but can handle upto a 5" (127 mm) drill pipe.The30 ft (9.1 m) multi pass tower provides a depth of 90 ft
I(27 m), using the standard 2-rod carousel combined
with a starter rod under the rotary head. A total depth Icapacity of 150 ft (45 m) can be reached when usingthe optional 4-rod carousel. A single fixed displace-ment axial motor powers the rotation of the head. A I
replaceable spindle adapter between the spindle andthe drill pipe is furnished as standard equipment,along with replaceable head guides. Pulldown andpullback cables are attached to the mounting plates,which are attached to the rotary head case. On the lowpressure version, 110 psi (7.6 bar) can be used for ra-tarydrilling ofblastholes upto 6~" (171I)1m) in diam-eter. On the high pressure version of the DM30, 350psi (24 bar) can be used for up to 6 in. DTH hammersand maximum 6 % in. bit diameter.

Operator comfortAll operational functions can be controlled tTomthe drillers console in the
cab. The ergonomic drilling console puts all of the drilling, tramming andauxiliary operations at the driller's fingertips and the operator has excel-lent visibility with an unobstructed view of the drill table. A nine-lighthalogen night lighting system is provided as standard for operator visi-bility under low light operating conditions. The cab is thermally insu-lated, pressurized, equipped with tinted safety glass and has an ergo-nomic seat with a seat belt.An additional safety feature is the integratedFOPS (Falling Object Protection System) structure of the cab. A heat-er/ventilator also comes standard. The air conditioning unit features adual circulation system allowing the operator to control the blowerspeed to regulate flow through the air conditioner evaporator, as wellas the fan speed of the tTeshair re-circulation system.
Efficient power packThe DM30 power pack consists of a diesel engine directly coupled toan air compressor on one end and a hydraulic pump drive on the otherend. This complete power pack assembly is mounted on its own subbase which is, in turn, mounted to the rig's main tTame.The in-linedrive train configuration maximizes mechanical efficiency and theseparate "floating sub base" isolates the components from drilling andpropel shock loads, helping to maintain alignment'between them. Sep-arate air inlet cleaners with quick release dust drop covers are standardfor both engine and air compressor intake. A cooler for the hydraulicoil, compressor oil and diesel engine coolant is provided. Operationalambient temperature rating for the DM30 is up to 125°F (52°C).
Sturdy and powerfulThe DM30 utilizes an excavator-type undercarriage that's built to AtlasCopco specifications. Tracks are driven by a planetary gear system withtwo hydraulic motors rated at 136 hp (101 kW) each. Both tracks are indi-vidually controlled and act as an independent unit. The tracks are hydrauli-cally adjustable with a spring recoil system and equipped with 19.7" (500 mm)replaceable triple bar grouser pads. The Atlas Copco designed main tTameisa weld fabrication of rectangular tubing, verified by dynamic strain gauging. A"walking beam" oscillation yoke allows the rig to propel over uneven ground,while reducing torsional stresses on the main tTame.
